Abstract

The clinical spectrum of familial Mediterranean fever (FMF) expanded especially in the last fifteen years, so "protracted febrile myalgia" is now considered one of the clinical manifestations of the FMF. We present a 12-year-old girl who was admitted to the Pediatrics Clinic with fever and severe myalgia in upper and lower extremities lasting for 10 days before the diagnosis of FMF. Her genetic diagnosis was homozygous for M694V mutation. We emphasize that protracted febrile myalgia in some cases of FMF could be the first symptom during childhood. The case was presented with the review of the literature.
